SDK Beta 4 Released, Adds OpenGL ES Support, Code Signing Enforced

A new version of the iPhone SDK beta, version 4, was released earlier today. New features in the update include OpenGL ES support and the enforcement of a new code signing policy:

OpenGL ES support: The iPhone emulator will now be able to render OpenGL ES in applications, matching the capabilities of the iPhone 2.0 software.

Code signing enforced: iPhone applications will now need to contain a valid certificate (obtained from the restricted, $99, iPhone Developer program) in order to be loaded on actual devices. If a developer does not have a certificate, apps will still run in the simulator but not physical devices.
